New range
of cost optimised linear position sensors has open housing and
two-part design.

Two part,
wiper and open housing design uses conductive plastic technology
for robust, long life, high accuracy position sensing applications
with practical pricing.
Variohm EuroSensor has launched a new range of potentiometric
linear position sensors for precision measurement from 10 mm
to 300 mm that are supplied in open housings - reducing component
cost for high accuracy position feedback applications. The PTP
series from Novotechnik is a robust two-part design including
a multi-fingered wiper assembly and separate open sided extruded
aluminium housing containing a conductive plastic track.

This design facilitates
straightforward mounting to equipment where sealing against dust
or fluid is not necessary, or where customers are able to integrate
these component parts within their own sealing arrangements.
The PTP series also allows for a wide variety of feature customisation
suited to high volume applications.

The extruded
housing has a cross section of just 13 mm x 9.6 and includes
longitudinal slots for convenient mounting with optional fixing
clamps or alternative fixing available via pre-drilled holes.
The inner profile provides a rigid, low friction bearing surface
for the wiper assembly which includes threaded hole, follower
pin and rod driving options - allowing complete design flexibility
within the customers application.

The conductive
plastic resistance elements comprise multiple printed layers
using Novotechniks own specialised conductive inks in combination
with multi-fingered precious metal wipers featuring a unique
elastomer damping mechanism to maintain complete contact even
under the most demanding working conditions.

The PTP series
specification includes a typical life of 50 million movements
with a vibration rating to 20 g at 2000 Hz and shock to 50g.
With a speed capability to 10 m/sec, repeatability to 0.01 mm,
and linearity to +/- 0.05%, these sensors are aimed at high accuracy
and high reliability position measurement in clean environment
applications or within customer sealed housings.

The PTP series
is part of a wide range of Novotechnik contacting and non-contacting
angular position sensors available exclusively in the UK and
Ireland from Variohm EuroSensor. Novotechniks conductive
plastic technology is well proven across large volume industrial
and automotive applications for both rotary and linear position
measurement in fully sealed and open designs with a numerous
mounting styles and grades of precision including dual redundancy
versions, and with customisation readily available to suit specialised
applications.
